    "abstract": "We propose a scheme by which two parties can secretely and simultaneously\nexchange messages. The scheme requires the two parties to share entanglement\nand both to perform Bell-state measurements. Only two out of the four Bell\nstates are required to be distinguished in the Bell-state measurements, and\nthus the scheme is experimentally feasible using only linear optical means.\nGeneralizations of the scheme to high-dimensional systems and to multipartite\nentanglement are considered. We show also that the proposed scheme works even\nif the two parties do not possess shared reference frames.",
